There are so many things that can put your teeth at risk.

Soda, medications, dry mouth, lack of oral hygiene, calcium shifts from drugs, or metabolic disorders. its VERY important if you have a disease process going on to seek dental care more often. During chemo I went once a week to the dentist, and he would paint my teeth with a protection gel. I was vomiting so much, the stomach acid was erroding my back teeth. The meds made my mouth so dry that I was seeing decay develope before my eyes! There are many things a dentist can do other than pull your teeth, but you have to show up early to give him a chance.

Now, get brushing!
